SPECIFICATION forming part of Letters Patent No. 611,644, dated October 4, 1898. Application filed November 22, 1897. Serial No. 659,438. (No model.)

To @ZZ whom, it may concern:

Be it known that I, GEORGE W. NOBLE, a citizen of the United States, residing at Lum, in the county of Lowndes and State of Alabama, have invented` certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in cultivators, its object being to provide a novel and simplified construction of combination implement adapted to be readily and conveniently converted, as desired, into a plow, a harrow, or a rake.

To this end the invention consists in the novel construction and combination of parts hereinafter more fully described, and pa-rticularly pointed out in the appended claims.

In the accompanying drawings, forming a part of this specification, like reference characters designate corresponding parts throughout the several views.

Figure 1 is a perspective view of my improved cultivator as adapted for use as a plow; Fig. 2, a similar view, but showing the plow-shovels removed and a harrow-frame substituted therefor; Fig. 3, a bottom plan view showing a rake-bar applied; Fig. 4:, a bottom plan view of a portion of the cultivatorframe, showing the manner of connecting the barrow-frame bars; Fig. 5, a bottom perspective view of the box or sleeve casting; Fig. 6, a top perspective view of same; Fig. 7 a broken detail perspective view of a harrowframe, showing the attaching-plate; Fig. 8, a perspective view of the adjustable yoke-plate clamp, and Fig. 9 a vertical section of same.

Referring now more particularly to the accompanying drawings, 1 represents the main beam ot' the cultivator-frame, provided at one end with a clevis 2 and at the other end with handles 3, and Li 5 represent short carrier beams or bars arranged on opposite sides of the main beam and parallel therewith. These carrier-bars are supported and adj ustably connected relatively to the beam, to vary the width of the frame, by two transverse metallic connecting-bars G, bolted centrally to said beam and formed with alined longitudinal series of orifices 7, with which bolts 8 on the carrier-bars are adapted to engage.

Braces 9 connect the front ends of the carrier-bars to the beam. These braces are secured at their front ends to the beam by means of a bolt and wing-nut l0 and are formed at their rear ends with longitudinal slots 11. Bolts 12 on the carrier-bars project through these slots and are fitted with win gnuts.

The beam and carrier-bars are each pro vided with a box or sleeve casting fitted to slide thereon and serving as an attaching device whereby plow-teeth, a harrow-frame, or a rake-bar may be secured thereto toconvert the cultivator into a plow, a harrow, or a rake at will. This consists of' a box or sleeve 13, adapted to encompass the beam or bar and formed with top and side flanged plate eX- tensions let 15 to rest upon the top and side of the beam or bar, as shown. The top Hangeplate 14 is provided with two parallel transverse lugs 14 and the side flange-plate with a single transverse lug 15% The top and bottom plates of the sleeve 13 are formed with alinedrbolt-oriiices 1G, and said bottom plate is also formed with a series of radial lugs 17, arranged con centric with its orice. A yoke clamp-plate 18, provided on its under side with yoke-arms 19, having alined bolt-receiving orifices 20, is formed on its upper side with a correspondingseries of radial lugs 2l, arranged concentric with an orifice 16a therein, adapted to engage the said lugs 17. The orifice 16a of the plate is countersunk to receive the head of a bolt 22, which passes up through the sleeve-orifices 16 and either one ot a series of orifices 23 in the beam and side bars and serves to secure the yoke clamping-plate to the sleeve as well4 as the sleeve to the beamror bar on which it is fitted. It will be readily understood that by loosening this bolt the yoke-clamp may be released from the lugs 17 and turned to set its yoke-arms at any angle desired relatively to the sleeve and that by tightening the bolt the clamp will be again rigidly held in adjusted position. y

Figs. 1, 2, and 3 of the drawings illustrate the-manner of forming the different combinations. In adapt-ing the device for use as ICO a plow I provide shovel plow-teeth 24, each formed with a vertical shank 25, adapted to rest against the lug 15 and having a threaded Orifice and a lateral arm 26, adapted to take between the lugs 14 and rest upon the top flanged plate 14 of the sliding attachingsleeve. By this construction the plow-teeth will be held rigidly against rearward movement, while a set-screw27 is provided to engage a threaded opening in the sleeve and prevent the tooth from moving outward laterally or sidewise.

In adapting the device for use as a harrow the plow-teeth are removed and a V-shaped harrow frame 2S substituted therefor, as shown in Fig. 2. The side bars 2S of this frame are provided vat their meeting ends with fianged plates 29, apertured for passage of the bolt 101L to secure them to the front of the beam 1. The rear ends of these bars are fitted in the arms of the yoke-clamps 18 and secured therein by a bolt 3l passing through the orifices 20. To receive the said bars, the yoke-clamp is adjusted to bring its yoke-arms at a diagonal angle relatively to the side bars 4 5, as shown. In forming a rake the yokeclamps on the bars 4t 5 are adjusted to set their yoke-arms transversely of said bars, and then one of the bars 28 of the harrowframe is extended transversely of the frame and secured in said yoke-arms by the bolt 31, as shown in Fig. 3.

From the above description, taken in connection with the accompanying drawings, it will be seen that I have provided a cultivator susceptible of a variety of uses and in which the parts are adapted to be readily and convenientlyinterchanged in forming the several cultivator combinations. It will also be seen that, if desired, both the plow and harrow attachments may be secured to the frame and the ground plowed and harrowed at one operation.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is-

1. In a cultivator of the class described, the combination of a beam, side bars adj ustably connected therewith, and adjustable members on each bar provided with plow-teeth and harrow attachments, whereby a series of plow-teeth and a harrow-frame may be Secured to said bars independently or together, substantially as described.

2. In a cultivator of the class described, the combination of a beam, side bars adj ustably connected therewith, and a sliding sleeve on each bar provided with plow-teeth-holding devices and a barrow-frame or rake-bar-attaching device, adjustable to receive the diagonally-extending bars of a harrow-frame or a transversely-extending rake-bar, substantially as described.

3. In a cultivator of the class described, the combination of a beam, side bars adjustably connected therewith, and an attaching device on each beam and bar comprising a box or sleeve having radial lugs on itsunder side and top and side flanges provided with holding-lugs to receive the shank of a plow-tooth and an adjustable yoke-clamp formed with radial lugs to engage those on the sleeve and yoke-arms to receive the side bar of a harrowframe or a rake bar, substantially as described.

4. In a cultivator of the class described, the combination of a beam, side bars arranged parallel therewith, connecting-bars adjustably connecting said beam and side bars, and an attaching device on each side bar comprising a sleeve provided with bolt-openin gs in its top and bottom plates and radial lugs on said bottom plate 'concentric with its opening, fianged top and side plates having holdinglugs to receive the shank of a plow-tooth, and an adjustable clamping-plate provided with yoke-arms and radial lugs adapted to engage said lugs on'the bottom of the sleeve, substantially as described.

5. In a cultivator of the class described, a beam, side bars arranged parallel therewith, connecting-bars adjustably connecting said beam and side bars, and an attaching device on each side bar comprising a sleeve provided with bolt-openings in its top and bottom plates and radial lugs on said bottom plate concentric with the opening, fianged top and side plates having holding-lugs to receive the shank of a plow-tooth, and an adjustable clamping-plate provided with yoke-arms and radial lugs adapted to engage said lugs on the bottom of the sleeve, in combination with a V-shaped barrow-frame having two detachable tooth-carrying bars adapted to be secured to said side bars by the yoke-clamps, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE W'. NOBLE.
